Definitions
- the invention relates to a controllable two-way valve device for an internal combustion engine with a housing in which a first inlet or outlet channel and a second and a third optionally with the first inlet or outlet channel corresponding outlet or inlet channel is arranged, wherein a valve rod the two-way valve device via an adjusting unit continuously translational is movable.
- Such controllable two-way valve devices are for example as combined Exhaust gas recirculation and bypass valve devices are known in which two valve members be operated via a continuously adjustable actuator to the Reduce pollutant emission of an internal combustion engine, in which in the warm-up phase the exhaust gas is passed through the bypass channel and after heating a Catalyst, the exhaust gas supplied via the exhaust gas cooler of the internal combustion engine becomes.
- an exhaust gas recirculation system with a valve device described which has an exhaust gas inlet and two exhaust gas outlets, wherein one of the exhaust gas outlets leads to a radiator and the other exhaust gas outlet is fluidically connected to a bypass channel bypassing the radiator.
- a housing of the valve is between the exhaust gas inlet and the two exhaust gas outlets each arranged a valve seat, of a plate-shaped valve member is mastered.
- the valve member is arranged on a valve rod, which has a Actuator is continuously movable and the second closer to the actuator arranged Valve member is on a second tubular surrounding the first valve stem Valve rod fixed.
- the actuator is designed so that in the Actuator two springs are arranged, over which the two valve plate biased pressed on their valve seats.
- the inner and outer valve rod are each arranged displaceable to each other, so that the pneumatic or electromotive Setting unit is designed so that depending on the direction of movement only one of the valve rods and thus only one of the two valve members from corresponding valve seat is lifted.
- valve assembly for controlling a recirculated exhaust gas flow described, this behind a bypass channel and an exhaust gas cooler are disposed so that this valve assembly has two inlets and having an outlet.
- the two each corresponding with a valve seat on the valve stem arranged valve members are about two in the channel each arranged coil springs pressed on the valve seat.

- valve devices in different applications, these are usually controlled electromagnetically.
- These valves are usually designed so that exactly two or three different positions to connect the different ones Paths to each other can be controlled.
- These are usually not continuous adjustable and suitable, for example, not for regulated exhaust gas recirculation via a radiator or a bypass, since the moving in the current Anchor would be sensitive to dirt and sufficient flow cross sections in such Valves are not guaranteed.
- valve spool in an air intake pipe which contains control ports, with an insertion and openings in the wall of the air intake pipe correspond, so that by a translational movement of the valve spool, which cylindrical is executed, a recirculated exhaust gas amount can be controlled.
- valve spool is not suitable as a controllable two-way valve device.
- the actuators in a version with two in one another running valve rods is therefore very expensive.
- the inner circumference of the lateral surface substantially corresponds to one Outer circumference of the inner of the two concentric outlet or inlet channels and the outer circumference of the lateral surface is smaller than the circumference of the surrounding Housing through which the third output or inlet channel is formed.
- the control openings to the interior of the two concentric or inlets, thereby providing a volume control to that exhaust or intake duct is made possible by the surrounding housing.

- the height of the control openings corresponds essentially the distance between the flared portion of the valve member and an extension formed in the outer concentric outlet or inlet channel with closed valve seat. This ensures that as soon as the fluidic Connection to the inner outlet or inlet channel by closing the Control opening is interrupted, now a current in or out of the outer output or Inlet channel can be made, which in turn in its size by the position of the Valve member is adjustable, since the extension of the valve member with the corresponding Extension of the outer concentric outlet or inlet channel corresponds and thus different flow cross sections are adjustable.
- the outer outlet or inlet channel has a constriction wherein the flow cross section dominated by the second control surface between the outer diameter of the inner outlet or inlet channel (7) and the inner diameter of the housing (8) arranged in the region of the constriction is and with the valve seat closed, the distance between the Valve rod pioneering edges of the control openings of the valve member and the to the valve rod facing edges of the control openings of the exhaust or inlet channel essentially the distance between the pointing away from the valve stem Edge of a cylindrical portion of the valve member and the constriction the outer outlet or inlet channel corresponds.
- the two-way valve device is in one Exhaust gas recirculation line arranged, wherein in the flow direction in front of the two-way valve device an exhaust gas cooler is arranged, which is located above the inner or inlet channel, which serves as a bypass channel and inlet channel, is bypassed and wherein the first inlet or outlet passage as the outlet channel to a suction pipe of the Internal combustion engine is used, and the third exhaust or intake passage as an intake passage serves, which is fluidly connected to the exhaust gas cooler.
- the arrangement behind the exhaust gas cooling device has the great advantage that the valve device on the colder exhaust gas recirculation side is possible, whereby the heat input into the valve or the actuator is reduced.
- the valve is simultaneously used as an exhaust gas recirculation valve and used as a cooler / bypass control valve, with only one Valve member is required to both streams independently in their amount regulate.
- the outer inlet channel formed by the exhaust gas cooler in the interior of which the bypass line is arranged. This significantly reduces the footprint of the entire facility, so that the entire Device with cooler, bypass and exhaust gas recirculation valve manufactured as a unit can be.
